- All ofthe penis Yof the mold-frame, including the mold-emersi are flush on top.Y so that the 'lejwth concrete or other iped, and said materiel surface to mold the buildeldesired article. The cores Y -bleelfiY 1 oiningitheln 'tudinal sides of the moldlame are esene Vtnereto b means of bolts 16 snil'w'erefnot se orted y coreholders upon t Esse; Y s construction may, howevei; eenged and these end eeres held inn pl y core-holders on the base when desire i tninegl; rfi?, W ich in turn i a "te'siepe 3, as shown. Transverse dlisiifes 'ere arten ed eeross thes'peees i IOC and cores is provided the traveler C, which is constrlucted as follows: Trucks F and G, forming terminals of an overhead brid eframe 17, are ada ted to move upon t e tracks 18 and 19, wliich are parallel with and arranged on each side of the series of moldforms A, as shown in Fig. 10. The overhead bridge-frame spans across the row of moldforms and is skeleton in form and built interal` with each terminal truck. On this ame is a pair of lon itudinal shafts 20, each shaft being provide with` a series of cabledrums 21; one drum for each end of each pair of division'sides 8. Each drum has a winding-cable 22, upon the free end of which is a hook 23. When all of the sides of the moldframe are released by removin the clam s 11, the longitudinal sides are ifted by t e pulle -blocks and chains 24, which are fastene to any convenient art of the overhead bridge-frame 17. The ower pulley-blocks carry hooks 25, which are passed through loops 26 u on "each end of each longitudinal side. Eac set of pulley-blocks and chains is o erated to lift the longitudinal sides from t e base and above the molded blocks. Said sets of pulleys and chains are of ordinary construction and are ada ted to hold the sides in raised position.` en ythe longitudinal sides are lifted, the division sides forming each pair collapse. The hooks 23 are passed through holes 27 in the ends of each pair of division sides, and by turning the cranks 28 and 29 the drums 21 are revolved and Wind their respective cables. This operation raises the division sides above the molded blocks. Ratchet-wheels and dogs 30 and 31 on each of the shafts 2() revent the division sides from lowerin he cranks 28 are connected with the sha ts 2O by means of intermediate sprocket-wheels 32 and chains 33. These sprocket-wheels may be of any desired relative size. So that a helper may assist in raising the division sides, handles 36 are fastened to the opposite ends of the shafts 20. A lifting-shaft 37 is journaled on said brid eframe between and parallel with the shats 20. This lifting-shaft carries a drum 38 above each mold E and-set of cores therein. A horizontal rod 39 is suspended, by means of a cable 40, from each drum 38 and carries a series of hooks 41, which are adapted to be passed through the engaging pieces 15 on the cores. The shaft 37 has connected therewith on one end a sprocket 42, chain 43, and a handle 44, which by turning revolves the shaft 37 and winds the cables 40 upon their drums and raises the cores above the molded blocks. A ratchet-wheel 45 and dog 46 are adapted to prevent the shaft 37 reversin after the cores have been raised. After a of the sides of the mold-frame and mold-cores have been raised above the molded blocks the traveler may be moved ov'er an empty mold-form and upon the tracks by applying l siales hand pinch-bars (not shown) to the wheels 47 of the terminal trucks. The sides of the mold-frame and cores may then be lowered and used again in constructing a new moldframe, while the molded blocks remain in the first form to set and to be removed from the base. The cores are placed over the moldcore holders on the base, and the sides of the mold-frame are clamped together in place upon said base after t ey have been lowered from the traveler. It is not necessary to remove the arting-wall 6 with the other parts of the mo d-frame, thou h when desired it may be lifted and carrie by the traveler by hooks and chains similar` to those indicated by the reference-numeral 24.

Concrete or other molding material is conveyed to the mold-frames b means of a carrier H. A bucket I is detacliabIy fastened to the carrier by means of hooks 48 and after being filled is moved to be enga ed by the carrier by means of a truck 49. his truck is movable u on a track 50, which is parallel with the trac 19 and adjacent thereto. The. carrier has a air of antifriction-rollers 51, which run in t e grooves of a track 52, (see Fig. 2,) carried upon the brid e-frame 17 of the traveler. The bottom of t e bucket has a hinged door 53, which is locked when closed by hooks 54 and is opened by releasin said hooks to permit the contents of the buc et to drop into the mold-frame. The carrier is moved back and forth-u on the track 52 by means of cables 55, whicli are looped around pairs of rollers 56 and 57. These pairs of rollers are mounted upon shafts 58 and 59, which are journaled upon the bridge-frame. The ends of the cables are fastened to collars 60 on a shaft 61, which supports the carrier H. A crank 62 is mounted u on the shaft 58, which by turnin is adaptedpto turn the drums 56 and 57 an move the carrier. Sprocket-wheels 63 and a chain 64 are connected to the shaft 59, and a crank 65 is operatively connected with said sprocket-Wheels, so thatan operator stationed at the other end of the bridge-frame may move the carrier. ,After the mold-frame has been filled with concrete or other molding material by means of the carrier it is tamped and evened off on the top of said frame and the operation of liftin the parts of the mold-frame and movin t e trucks is repeated.

he action of each pair of division-plates collapsing together as described produces a cleaner-cut block and enables the removal of the division-plates without mutilating the blocks and reduces the number of moldframe parts necessary for manufacturing a given number of blocks.

It is obvious that the operation of molding as described is substantiallr continuous and that practically no time is ost in the use of the apparatus and that a large number of IIO building-blocks may be made by a single op- 13o A machine of the class set forth, comeration, Whereas with other rior art machines more hand-labor and time are necessary for manufacturing a given number of blocks.

Asshown in the alternate construction, a single 'series of double molds is formed by a single frame 66. Track-rails 67 are laid upon the base,so that a truck 68 is adapted to move above the mold-frame. A Winch 69 is carried by the truck and is o erated by sprocket-wheels 7 @connecting c ain 71 and crank 72 to revolve drums 73 and wind cables 74 thereon. The ends of these cables are attached to a cross-bar 75, which carries a number of hooks 76 to engage and lift the cores and the division sides out of the molds D. The longitudinal sides of the mold-frame ma be removed by hand and are of substantiallry the same construction as in the, preferred form. The sides and cores removed may be placed 'upon the truck 68 and removed on the track 67. Y

it is obvious that the construction above set forth may be changed and varied without departing from the spirit of this invention, and I do not limit or confine myself to the exact construction described.
